Abstract: Objective To understand the epidemiological characteristics and trend of injury mortality among children aged 5~19 from 2008 to 2014 in Xi'an city,and to provide evidence for making related interventions. Methods Data were derived from the disease death surveillance database during 2008 to 2014.ICD-10 was used to classify death causes.Mortality rate,proportional mortality indicator and annual percent change(APC) were calculated and analyzed. Results Mortality in injured deaths was 14.01/10⁵,which showed a descending tendency with the average decrease rate of 3.23%.The mortality in boys was higher than that in girls,and the mortality in boys showed a descending tendency(APC=-5.58%,t=-4.04,P<0.05).The first 5 kinds of injury death causes were traffic accidents,drowning,accidents,suicide and accidental poisoning,which accounted for 87.92% of total injury mortality among children aged 5 to 19 years old. Conclusions The injury mortality of children aged 5~19 years old showed a descending tendency.Traffic accidents and drowning are major causes of injury death.The damage prevention and control from family,school and social should be strengthened to reduce the injury mortality of young people.

摘要： 目的 分析西安市5～19岁学龄期青少年伤害死亡原因及变化趋势,为制定伤害干预措施提供依据。方法 收集西安市2008-2014年伤害死亡资料,用 ICD-10 进行死因分类,计算伤害死亡率、死因构成、年度变化百分比(Annual Percent Change,APC),并进行统计分析。结果 西安市2008-2014年5～19岁青少年伤害平均死亡率为14.01/10⁵,总体呈逐年下降趋势(APC=-3.23%,t=-2.78,P<0.05);男性青少年伤害死亡率高于女性(χ²=111.72,P<0.01),男童伤害死亡率随年份的增长呈下降趋势(APC=-5.58%,t=-4.04,P<0.05)。前5位伤害死亡原因依次为交通事故、溺水、意外事故、自杀和意外中毒,占该年龄伤害死亡的87.92%。结论 西安市青少年伤害死亡率呈逐年下降趋势,交通事故和溺水是主要死亡原因,要从家庭、学校和社会三方面加强伤害防控,以有效降低青少年伤害死亡率。
